I mentioned before that I have been looking at systems to use for a Hyborian Age campaign eventually; something that matches up to the weird pulp fantasy feeling one gets when reading Howard (and Lovecraft, and Smith, and Leiber...).
D. and I were talking recently about Labyrinth Lord, and I also want to check out OpenQuest. I need to investigate the damage dice variation for Action Cards, too.
Now, another possibility: Stuart at Strange Magic will be following up on his excellent Weird West RPG with Weird Fantasy. So many good choices!
